Vegan Diet: Feeling Waterlogged And Heavy?

A vegan diet can be a healthy choice, with numerous health organisations endorsing the adoption of this dietary pattern. However, some people experience side effects when transitioning to a vegan diet, one of which is feeling waterlogged or bloated. This can be attributed to the high fibre content of vegan diets, as the body needs time to adjust to the increased intake of fibre. Additionally, not consuming a diverse range of plants or being unaware of the foods needed to meet daily nutritional requirements can lead to vitamin and mineral deficiencies, which can also contribute to feelings of waterlogging or bloating.

High-fibre vegan foods can cause bloating

Bloating is a common side effect of switching to a vegan diet. This is because vegan diets are typically high in fibre, which can overload the body. Fibre is present in vegetables, fruits, and grains, and while it has many health benefits, it can cause bloating when consumed in large quantities.

The increase in fibre can be a shock to the body, especially if you were previously consuming a low-fibre diet. It takes time for your gut bacteria to adjust and process the additional fibre, especially that from legumes. As a result, you may experience bloating and other digestive issues during the initial transition period.

To manage bloating, it is important to drink plenty of water, as this helps to push fibre through the digestive tract. Additionally, including probiotic foods such as miso, sauerkraut, and kimchi can be beneficial. While the bloating should subside within a couple of weeks, it is worth noting that it may take longer for your body to fully adjust to the high-fibre content of a vegan diet.

It is also worth noting that not all vegan foods are created equal when it comes to fibre content. Soy products such as tofu, tempeh, and soybeans are excellent sources of protein and are generally well tolerated by the digestive system. Legumes, on the other hand, are high in fibre and can be more likely to cause bloating, especially when consumed in large quantities.

If you are experiencing bloating, it may be helpful to gradually introduce high-fibre foods into your diet and monitor your body's response. Additionally, soaking legumes before cooking them can make them easier to digest. Canned beans are also typically gentler on the stomach, as the canning process helps to break down some of the fibres.

A vegan diet may not provide enough calories

It is a common misconception that vegan diets are not calorie-dense. However, there are plenty of vegan foods that provide calories similar to animal foods, and in smaller portions.

Calorie-dense vegan foods

• One-half avocado weighing 3.5 ounces contains 160 calories — about the same amount as a cup of whole milk.
• One ounce of walnuts provides 180 calories, which is slightly more than 1.5 ounces of cheddar cheese.
• Two tablespoons of creamy peanut butter have 190 calories — 25 calories more than a 3.5-ounce chicken breast without skin.
• One tablespoon of olive oil provides 119 calories — about the same as 3 ounces of sockeye salmon.

Other calorie-dense vegan foods include quinoa, dried fruit, black beans, sweet potatoes, brown rice, and coconut oil.

High-fat vegan foods

The most caloric vegan foods are high in fat, such as nuts, oils, and avocado. But unlike animal fats, high-fat vegan foods contain mostly monounsaturated and polyunsaturated fats, which can benefit your heart and lower your LDL cholesterol.

High-protein vegan foods

Another misconception is that it's difficult to get enough protein on a vegan diet. However, there are plenty of plant-based sources of protein, including grains, legumes, nuts, seeds, and even some vegetables. Some examples include seitan, lentils, chickpeas, hempseed, spirulina, green peas, and nutritional yeast.

High-calorie vegan foods

It is important to note that relying on processed and prepared vegan foods is not a healthy way to increase your calorie intake. Meat substitutes, frozen vegan meals, and sugary, salty snacks are highly processed and full of sugar and refined grains that can negatively affect your energy levels and damage your overall health.

Instead, focus on incorporating healthy, whole-food sources of calories into your diet, such as nuts, oils, avocado, quinoa, dried fruit, legumes, sweet potatoes, brown rice, and coconut oil.

Additionally, you may need to eat several meals a day to fit in enough calories. Try including some calorie-dense foods in each meal, and consider logging your food to keep track of your calorie and nutrient intake.

A vegan diet may lack essential vitamins and minerals

Additionally, the body's ability to absorb certain nutrients from plant-based sources can be limited. For instance, vegans may need to consume nearly twice the recommended amount of iron, as non-heme iron from plant sources is not as easily absorbed as heme iron from animal sources. Similarly, the body's absorption of non-heme iron can be further inhibited by the presence of anti-nutrients, such as phytic acid, in plant-based foods.

Moreover, a vegan diet may lack omega-3 fatty acids, particularly the long-chain types eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). While the body can convert alpha-linolenic acid (ALA), found in plant sources, into EPA and DHA, the conversion rate is very low. As a result, vegans may need to supplement their diet with omega-3 fatty acids to ensure adequate intake.

A vegan diet may also be deficient in vitamin D, as few foods naturally contain this nutrient. While vitamin D can be obtained through sun exposure, those with limited sun exposure or who live far from the equator may need to supplement their diet.

Finally, a vegan diet may lack calcium, as plant sources do not always provide sufficient amounts. This is particularly important for vegans, as insufficient calcium intake can increase the risk of bone fractures.

It is important to note that a well-planned vegan diet that includes a variety of nutrient-dense plant-based foods and considers supplementation can provide all the essential vitamins and minerals required for optimal health.

Vegan foods are digested more quickly

A vegan diet can lead to feelings of waterlogging or bloating, especially when transitioning from a meat-based diet. This is because vegan foods are typically higher in fibre and water content, which can take some time for the body to adjust to.

Secondly, the fibre content of vegan foods is higher, and fibre sweeps food through the digestive tract more efficiently. Fibre cannot function without water, so the high water content of vegan foods also plays a role in speeding up digestion.

Additionally, the body breaks down and absorbs different foods at different rates. Processed sugars and refined grains are absorbed within an hour, while fruits, vegetables, fish and eggs take around 2-6 hours to digest. Meat, dairy, legumes, whole grains, nuts and seeds take around 8 hours, and tough proteins and fibrous foods can take 12 hours or longer.

Finally, a vegan diet can be beneficial for gut health. Fermented vegan foods such as kimchi, kombucha, tempeh and miso contain active cultures that help maintain gut health. Vegan foods are also rich in probiotics and prebiotics, which are essential for a healthy digestive system.

However, it is important to note that a poorly planned vegan diet can lead to nutritional deficiencies, which may cause fatigue and other health issues.

A vegan diet may not provide enough protein

It is a common misconception that vegan diets lack sufficient protein. However, vegans can get protein from various plant sources, although some may be better than others. Research suggests that higher-protein diets can promote muscle strength, feelings of fullness, and weight loss.

According to the dietician and nutritional advisor Reed Mangels, only around one calorie out of every 10 consumed needs to come from protein to meet the body's needs. For a male vegan, this roughly translates to 63 grams of protein consumed daily, and for a female, it's roughly 52 grams. The exact amount can vary by weight, muscle mass, and other factors.

• Nuts, seeds, and nut butters: Almonds, flaxseed, hemp seeds, pumpkin seeds, chia seeds, cashews, and pistachios are good sources of protein.
• Tofu: Made from soybeans, tofu is an excellent source of protein, packing in 18 grams of protein per 100 grams.
• Beans and legumes: Kidney beans, peas, black beans, pinto beans, soybeans, navy beans, and peanuts are effective sources of protein and are also high in fiber and B vitamins.
• Chickpeas and lentils: Chickpeas offer 19 grams of protein per 100 grams, while lentils offer 26 grams per 100 grams. They are also good sources of fiber, potassium, iron, and manganese.
• Nutritional yeast: Nutritional yeast is a complete protein, offering all nine essential amino acids. Two tablespoons contain about nine grams of protein.
• Tempeh: A traditional Indonesian ingredient, tempeh is made from soybeans and is a delicious source of calcium, iron, manganese, and protein – boasting 15 grams per 84-gram serving.
• Vegan meat: Some vegan meat brands, such as Beyond Meat, offer patties and sausages made from peas and other plant-based ingredients. One Beyond Burger, for example, contains 20 grams of plant-based protein.

While it is possible to get enough protein on a vegan diet, there may be some challenges or considerations to keep in mind:

• Variety: Eating a varied, balanced diet is crucial to ensuring adequate protein intake on a vegan diet. This is because different plant sources of protein contain different amino acids, which are the building blocks of protein. By consuming a variety of plant-based proteins, you can ensure you're getting all the essential amino acids your body needs.
• Quantity: Depending on your weight, muscle mass, and activity level, you may need to consume larger quantities of plant-based proteins to meet your protein requirements. For example, vegan bodybuilders or athletes may need to aim for higher amounts of protein and may find it challenging to get this amount from whole plant foods alone. In such cases, vegan protein supplements can be helpful.
• Bioavailability: The protein in plant-based sources may be less bioavailable than that in animal-based sources. This means that your body may absorb and utilize a smaller proportion of the protein from plant sources compared to animal sources. However, this can be mitigated by combining different plant-based proteins and ensuring a varied diet.

In conclusion, while a vegan diet can provide sufficient protein, it is important to be mindful of your protein requirements and include a variety of plant-based protein sources in your diet to ensure you're getting all the essential amino acids.
